GetNormalizedCentralMoment

Retrieves the normalized value of the image central moment computed by ippiMoments.

Syntax

IppStatus ippiGetNormalizedCentralMoment_64f(const IppiMomentState_64f* pState, int mOrd, int nOrd, int nChannel, Ipp64f* pValue);

Include Files

ippi.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

pState

The structure that stores image moments.

mOrd, nOrd

Integer power exponents defining the moment order. These arguments must satisfy the condition 0 mOrd+nOrd 3.

nChannel

The channel for which the moment is returned.

pValue

Pointer to the returned moment value.

Description

This function normalizes the central moment value that was previously computed by the ippiMoments function, and returns the pointer pValue to the normalized moment. The moment order (mOrd, nOrd) is specified by the integer power exponents. SeeImage Moments for details of moments normalization.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or a warning.

ippStsNullPtrErr

Indicates an error condition if pState or pValue pointer is NULL.

ippStsContextMatchErr

Indicates an error condition if a pointer to an invalid structure is passed.

ippStsMoment00ZeroErr

Indicates an error condition if M(0,0) value is close to zero.
